Answer to Question #891 in Mechanics | Relativity for Jordan
A hot air ballon (with bucket) has a mass of 900 kg. The balloon has a buoyant force upward of 12,000 N and a westward wind force of 500 N. Find the acceleration of the balloon. What is the force of gravity (weight) of the balloon and bucket?
show work and answer
The force of gravity of the baloon with bucket is F = mg = 900 *10 = 9,000 N - downward. Let's find the vector sum of all forces: √ (12,000-9,000)2 + 5002 = 3041 N. a = F/m = 3041[N]/900[kg] = 3.4 [m/sec2]
Im very glad to use your service,last semester i used to stress over assignments even tho i knew how to do them but it used to put me in extra stress and specially having 5 courses with it made things hard,ever since i started using your service,it has removed alot of stress for me,im gettinf better grades now,100% in all my assignments till now,ive a humble resquest,i will keep following your website for many years,for your regular or frequent customers you should include some sort of discount other than that everything is perfect
